Abstract: PURPOSE:To obtain said calcined powdered body of good quality having comparatively uniform acicular grain size by heat-treating an amorphous body obtained by quenching a molten body of PbTiO3 at a specified temp., and calcining at limited temps. CONSTITUTION:A substance such as B2O3 which is not combined with PbTiO4 and forms a molten nucleus and which is not combined with PbTiO4 and helps the formation of amorphism is mixed by a wet method with powdered PbTiO4 on the market of high purity such as 99.9%. The mixed powder is dried, then preferably added with a small amt. of ethyl alcohol as a binding agent, molded into the form of a disk, for example, calcined at about 1,000 deg.C, and crushed. The powdered body of PbTiO3 is successively melted and quenched in an ultrarapid- quenching manufacturing apparatus of an amorphous body to obtain an amorphous body. The amorphous body is heat-treated by heating at about 500-540 deg.C and then cooling temporarily, then calcined at about 900-1,100 deg.C, and cooled to obtain plate-shaped pieces of a sintered body. The sintered body is crushed to obtain the desired powdered body of acicular PbTiO3 crystal particles.
